8. The heat dissipating assembly as claimed in claim 7 , wherein the plurality of curved latches are in line with each other, every two adjacent ones of the plurality of curved latches being located in each of the three regions on the bottom member of the flange.

9. The heat dissipating assembly as claimed in claim 7 , wherein each of the pair of arced latches extends along a horizontal orientation, and the each of the plurality of curved latches extends along a vertical orientation.

10. The heat dissipating assembly as claimed in claim 7 , wherein each of the pair of wire clips comprises an upward distal section, a pivoting section bent horizontally from the distal section, a pressing section formed upwardly from the pivoting section, another horizontal pivoting section connecting the pressing section, and an operating section extending upwardly from the another pivoting section, the pivoting section being engaged in a distal one of the plurality of curved latches, the another pivoting section being locked into two of the plurality of curved latches adjacent to the distal one of the plurality of curved latches, and the operating section being locked into a corresponding one of the pair of arced latches.

11. The heat dissipating assembly as claimed in claim 10 , wherein the pressing section of the each of the pair of wire clips comprises a pair of parallel connecting portions connecting the pivoting section and the another pivoting section respectively, and a bent portion extending inwardly from two ends of the pair of connecting portions, the bent portion being located above the top members of the flange.

12. The heat dissipating assembly as claimed in claim 11 , wherein when the operating section of the each of the pair of wire clips is pivoted to be locked into the corresponding one of the pair of arced latches, the pressing section is driven by the operating section to rotate, with the pair of connecting portions thereof pushing the fan to slide inwardly, and the bent portion thereof abutting downwardly against a bottom of the lateral side of fan to sandwich it with the pair of top members of the flange.

13. The heat dissipating assembly as claimed in claim 1 , wherein the second holder comprises a plate secured at the opposite lateral side of the heat sink, and a pair of strips extending horizontally and inwardly from a top of the plate for supporting the another part of the fan.

14. The heat dissipating assembly as claimed in claim 13 , wherein each of the pair of strips has an end divided into two pieces along a midline of a width thereof, one of which is bent upwardly and slantwise for abutting downwardly against a bottom of an opposite lateral side of the fan, and another of which maintains its original configuration and supports the opposit lateral side of the fan.

15. The heat dissipating assembly as claimed in claim 1 , wherein the heat sink comprises a base and a plurality of fins extending upwardly from the base with some of the plurality of fins each having an upper portion bifurcating upwardly to form a fork configuration, the first holder and the second holder being attached to the some of the plurality of fins.

16. A heat dissipating assembly, comprising: a heat sink; a fan mounted on the heat sink; a first locking device mounted on a first side of the heat sink and having a supporting plate extending beyond the heat sink, a part of the fan mounted on the supporting plate; and a second locking device mounted on a second side of the heat sink, the first and second locking devices cooperatively pressing two opposite sides of the fan to mount the fan onto the heat sink.

17. The heat dissipating assembly as claimed in claim 16 , wherein the first locking device comprises a pair of wire clips pivotably mounted on the supporting plate, each clip having a pressing portion pressing the fan when the clip is in a closed position.
